| Popis: | In this study, we analyzed the effect of fluoride ions on photocatalytic activity of titanium dioxide. Synthesized and calcined F-doped materials exhibit photocatalytic activity in the both UV and visible light range. The photocatalytic activity induced by UV exposure is higher than that of commercial material Degussa P25, which is pure titanium dioxide. Also the research on influence of fluoride ions on anatase-to-rutile phase transition was carried out by X-ray powder diffraction. The introduction of fluoride ions was found to increase the thermal stability of anatase modification of titanium dioxide. |
